Application filed January 2, 1915. Serial o. 101.

To all whom it. ma concern.

Be it known t at I, FRANK M. Primer, a: citizen of the United States, and a res1-.

dent of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shuttle FoldingandGuiding Devices; and

I do hereby-declare that the following is This inventlon relates to'an improved folding and guiding device for paper carried 1 upon a rotatable shuttle such as tire wrapping machines wherein the. tire or other article to be wrapped is placedin the machine and rotated while a shuttle carrying a '1 el of paper is rotated rapidly through'the eyethereof, applyinga wrapper helically thereto. 2 Heretofore th I guiding the paper to the article to be wrapped, and'the device is furthermore adjustably mounted upon the'shuttle so that the angle thereof may be changed according to the position of thearticle inthe machine, inasmuch as articles of different size are sometimes placed-in relatively different positions in the machin 1 when being wrapped.

' It is an Object tli efore of this invention to construct a device attachable to a shuttle 'adaptedto receive a strip of paper running therethroughv acting to. curl. the paper over to form a fold and the paper then being drawn around -a suitable extension on the device serving to crease said fold, and suitably guide the creased folded paper to the article being wrapped.

It is also an important objectof this invention to construct a unitary folding, creasingand guiding device which is adjustably mounted upon a shuttle carrying a reel of paper for application to an article to be wrapped.

Fig. 2 device Fig. 3 is a detail section taken on llne 3-3 of Fig. 2. -Fig. 4: is an interior strip ofpaperi-taken-from the reel carried P the shuttle h'asbeen v It is finally an object of this invention to construct a device simple in operation and construction, greatly improving the wrapping operation of the machine to whichit is attached.

The inventiop (in a preferred form) is Illustrated in the drawings, and is more fully pointed out and defined in the appended claims.

In the drawings: Figure l is a front face v ew Offl. shuttle equipped with a device embodying. the principles of my invention. is an enlarged outer face view of, the

face view of the device detached, from the shuttle.

-, As shown in the drawings, a. shuttle is 7 illustrated in Fig. 1, and consists of a main section 1, and a supplementary section 2, which is hinged thereto upon a stud bolt 3, and held locked in closed position by locking mechanism denoted as a whole by the refer- I once numeral 4, at the junction of said hingedly connected shuttle sections. Secured on the side face of the main shuttle section 1, is a'stud bolt 5; on which a paper carrylng reel 6, is journaled', and on which isdisposed a reel of'pa er 7. A tension device for the paper led rom the paper reel 6, is provided, comprising a plate 8, secured to the surface of said main shuttle section 1,

and provided with a group of rounded pins 9, 10 and 11, respectively, around which the paper is trained; From the-tensionmechanism the strip of paper is led to a folding,

of a sheet of metal 12, which is bent'upwardly from its lower edge, affording an upright plate, as indicated by the reference numeral 13, and which, as clearly shown in Fig.4, in dotted lines, tapers downwardly along its upper edge to a vertical cutaway creasing and guiding device which consists edge 14, and then tapers downwardly again,

therefromat an angle of about thirty degrees, although the particular angle is immaterial, to the bottom edge of the plate.

The upper margin of the sheet of metal 12, is folded Over and flared outwardly rearwardly of the device; that is, to ard the entrance end thereof, as denoted by the referenoe numeral '15, and increases njwidth, as clearly shown in Fig. 4, froin thej entrance end ofthe device toward the exitf'end thereof, and is there equal in depth to the width of the main plate 12. Integral with said folded extension 15, at the forward or wide end thereof, is a curved extension 16, which, as clearly shown in plan view in Fig. 1, is angled out of the plane thereof. The folder plate is secured upon a plate 17, which may be attached to the rear surface of the main plate 12, of the folder, in any suitable manner, said plate 17, having formed at one end a cylindrical member 18, through which a bolt 19, extends. The lower end 20, of said bolt 19, is bent at an angle thereto to engageperpendicularly throughan aperture in the wall of the shuttle section 1, and on said lower end 20, is a nut 21, which maybe loosened to permit adjustment of said bolt.

It is apparent, therefore, by reference to F ig. 3, that'the bolt 19, is always at an angle with respect to the surface of the wall of the shuttle section, and an angled washer 22, is engaged upon said angled bolt between the cylindrical member 18, and the surface of the shuttle section. The opposite surfaces of said washer are not parallel but at an angle formed to correspondwith the angularity of the bolt 19. It is therefore apparent that the folder device may be adjusted about the pivot bolt 19, into various positions, all of which. are angled with respect to the surface of the wall of the shuttle, and may be retained in any adjusted position merely by tightening the nut 21.

The operation is as follows: The paper is led from the paper reel and thence through the tension mechanism, and enters the folder plate at the end adjacent the cylindrical member 18, the lower edge of the paper strip tracking upon that portion of the metal connecting the plates 12 and 13, along the lower edge of the device. The upper edge contacts the flared, curved portion 15,

and is thereby folded over and downwardly around the upper margin of the plate 13.

Thus a fold is created in the paper, and as the same is drawn from the folder device around the curved member 16, thereof, said fold is creased and the crez'iscd paper is applied to the article. Inasmuch as the folder device is mounted upon the bolt 19, which is always angled with respect to the surface of the shuttle section 1, it is apparent that the proper tilt to the folding device is secured in all positions of adjustment, and the folder device may be readily adjusted by loosening the nut 21, and swinging said folder device into various positions.

I am aware that various details of construction and operation may be varied without departing from the'principles of this invention. I therefore do not purpose limit- .subscribing witnesses.

ing the patent granted, otherwise than necessitated by the prior art.

I claim as my invention:

1. In a device of the class described a plate bent to afford a portion parallel thereto with the edge tapered off and another portion bent thereover and flared therefrom and vtapered downwardly substantially uniformly with the taper of said other portion and terminating in a curved portion.

2. A device of the class described embracing a plate, one margin of which is bent thereover and flared outwardly along the upper edge, another portion of which is bent upwardly from the lower edge beneath said first mentioned portion, and a curved portion formed integral with. the end of said first mentioned bent portion.

3. In a device of the class described the combination with a shuttle, of a folder plate member pivotally mounted thereon at an' 2 angle thereto.

4. In a device .of the class described the combination with a shuttle, of stationary folding and creasing mechanisms adjusta'bly mounted on the shuttle an angle thereto. 5. In a device of the class described the combination with a shutt1e, of unitary folding, guiding and creasing means adjustably secured at an angle thereto.

6. In a device of the class described a folder plate adapted to receive paper drawn therethrough to fold the same, and a curved extension on said plate to crease the fold in the paper as it is drawn thereover.

7. The combination with a shuttle, of a pivotally mounted folder plate thereon, the

pivotal axis thereof inclined in two different 9. In a device of the class described, a.

pintle bolt mounted in an inclined position, a plate pivotallymounted thereon, a guide plate integral therewith tapered to afford a narrow restricted nozzle, and having one edge turned over said plate. to fold wrapping material thereover as it is drawn through said guide plate. 1
